The CPSC is a federal agency of the United States government. The CPSC seeks to promote the safety of consumer products by issuing and enforcing mandatory standards, banning or recalling unsafe products, researching product hazards, and educating consumers and manufacturers.
Publication 516 of the U.S. Consumer Product Safety Commission (CPSC), which was first published in 1984, and recently clarified by letter, highlights the difference between aluminum and CCA, namely by excluding CCA from remediation recommended for homes built from the 1950s to the 1970s that were wired with small circuit aluminum conductors.
In a 2023 letter from the CPSC Director – Division of Electrical Engineering and Fire Sciences, Andrew Trotta clarified that the CPSC does not recommend that Copper-Clad Aluminum (CCA) wire be remediated, as it does for aluminum wire. Rather, the CPSC recognizes by its letter that CCA is suitable for direct connection to copper conductors and copper-rated 15 and 20 ampere wiring devices.
